/* Note: This code is an example of *bad* style and serves
 * only to illustrate the issues involved:
 *
 * First: overloading between int and unsigned often leads to ambiguities
 * Second: relying on the promotion type of an enumeration to determine
 *         which function is matched is inherently machine-dependent.
 * A better design would include a specific 'format' function that took
 * an argument of type 'e2'
